Benefits of technology

The solution ensures reliable and accurate glucose monitoring by efficiently transporting small blood volumes from the wound site to the sensor, reducing the time required for fluid transport and improving the consistency of blood droplet formation and measurement.

Problems solved by technology

The problem might be due to shallowness of the penetrating member penetration depth, skin surface tension issues, or the patient's vascular conditions resulting in the invariability in achieving an adequate blood droplet shape and size.

Embodiment Construction

[0046]It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed. It may be noted that, as used in the specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a material” may include mixtures of materials, reference to “a chamber” may include multiple chambers, and the like. References cited herein are hereby incorporated by reference in their entirety, except to the extent that they conflict with teachings explicitly set forth in this specification.

[0047]In this specification and in the claims which follow, reference will be made to a number of terms which shall be defined to have the following meanings:

[0048]“Optional” or “optionally” means that the subsequently described circumstance may or may not occur, so that the descr...

Abstract

A system and method is provided for the capture of bodily fluid upon lancing of a patient. In one embodiment, the fluid sample capture aperture mesh (320) ring is placed in the pathway of a finger penetrating member (340). The aperture mesh ring has a center clearance area that allows the penetrating member to pierce the skin unobstructed. The aperture mesh ring may contain a series of fluid sampling meshes as to allow the release bodily fluid to “wick” into the fluid sampling meshes for transport to the respective sensor. The invention may also relate to a method of improving the fluidic flow through a membrane mesh structure for the transportation of bodily fluids from a point of sampling to a point of measurement.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 533,981, which application is fully incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to the collection of body fluid and specifically, the transfer of fluid from the tissue to a sampling device.[0004]2. Description of Related Art[0005]Treatment of diabetes requires frequent monitoring of levels of blood glucose. This is traditionally done in a series of steps involving the preparation of a lancing device, preparation of a glucose meter, lancing a finger, transporting the resulting blood drop to the meter, and finally obtaining a blood glucose reading.[0006]Lancing devices are known in the medical health-care products industry for piercing the skin to produce blood for analysis. Biochemical analysis of blood samples is a diagnostic tool for determining clinical information. Many point-of-care test...
